Sway bar drop links tend to fail first. They are cheap and easy to replace. They create all manner of rattles depending on driving conditions. Definitely should have the car checked out by a mechanic. Suspension is a wear item and can add up if you do a complete refresh to the point where you might say why bother. But rattles are annoying which is why I say have it checked out and get the necessary parts fixed then keep driving until it needs a little more work. You are never going to have a showroom perfect car unless you don’t drive it.

Lots of things contribute to rattles. I have done a few suspension repairs such as drop links as mentioned here. Also another source of rattle for me was the clips for the window screen. My clips had worn so the screen rattles excessively in the bracket. This was a $7 fix.
